UCC218XXXEVM-111
Overview
The UCC218XXXEVM-111 is a compact, half-bridge gate driver board consisting of two single-channel isolated gate drivers. It provides isolated bias supply, drive current, protection and monitoring needed for driving several different models of Wolfspeed silicon-carbide (SiC) MOSFET modules and other IGBT or SiC MOSFET modules with a similar pinout. The onboard isolated bias can provide adjustable isolated voltage with passive component change.
The board's compact form factor, combined with UCC218XXX's 5kVrms reinforced isolation, makes it a good candidate for doing high-voltage tests, such as double-pulse tests and short-circuit tests, with the Wolfspeed SiC modules. The board can also be used with all variants of the UCC218xxx with minimal onboard modifications.
Features
- Fully compatible with UCC218xxx family of isolated gate drivers
- Directly compatible with Wolfspeed's FM3 and XM3 modules
- UCC34141 isolated bias to provide positive and negative bias to the secondary side
- Status LEDs indicate power-good and fault feedback from each driver
- Test points for all critical nodes to expedite debugging
- Ability to install external buffer to increase drive strength
